Toggles is a game of deduction, not luck. These are the rules the game holds itself to. The tools that build each season check every one of them before a toggle can be used.
One public source per toggle
Every toggle follows exactly one free, public source: a value anyone can read on a web page without paying, signing up, or installing anything. Providers sometimes disagree slightly about the same thing, so finding the right source is part of the puzzle.
Published before the snapshot
Each day's value is final and public by 10:00 UTC, when Toggles takes its snapshot. Nothing that moves by the minute, changes during the afternoon, or is settled after the lock is ever used. If a source revises a value later, the snapshot stands.
Every answer is knowable before the lock
Boards lock at 23:00 UTC. Between 10:00 and 23:00 UTC, you can look up everything you need to get every active toggle right. A perfect run is earned by deduction, never by luck.
Only these steps
A source's value reaches its toggle through a short chain of these steps and nothing else. There's no hidden formula and no hand-picked answer.
- Direction
- Whether a number went up, went down, or stayed the same compared with an earlier day, usually the day before.
- Parity
- Whether a number is odd or even, judged by its last digit at a set number of decimal places. On means odd.
- Last digit
- The last digit of a number, written to a set number of decimal places, so 1.0874 to four places gives 4.
- First letter
- The first letter of a piece of text, A to Z, skipping digits and punctuation and ignoring accents.
- Threshold
- Whether a number is above a set level. On means above.
- Bucket
- Which of a few set ranges a number falls in, such as under 2, 2 to 4, or 4 and over.
- Modulo
- The remainder after dividing a whole number by a set number, like a clock wrapping around.
- Rank
- Which of several numbers from the same source is highest, or all of them in order, by value, by how much each rose since the day before, or by what percent each rose.
- Equals
- Whether a value is exactly a set value, such as the color being red or the direction being up. On means it is.
Nothing changes mid-season
Once a season starts, its rules are fixed. The one exception is a source that breaks for good: its toggle is swapped for a reserve from the next day, in the same place on the board. You get three days of the reserve's past answers up front, and its first three days don't count, so no streak can break on a rule you haven't seen yet.
If a source fails on a given day, every toggle using it is out of service that day. It doesn't score and it doesn't break your streak.
Two toggles are yours alone
Two toggles on every board follow your own history, such as yesterday's score. Rules can leak between players, but nobody can copy a whole perfect board from a friend.
An account is required
You sign up with a public username and a verified email address, so each board belongs to one person. Your email is never shown.
Where to start looking
Every source is free and public. Lists of public data, such as public-apis on GitHub, are a fine place to start. Some sources are on that list and some aren't.
